. 28 C i s.

The invention relates to the art of banding and wrapping cigars and moreparticularly to the simultaneous application of the band and wraper to acigar by the operation of a single.

machine. Among the objects of the invention are First, to provide forhandling cigars of all sizes by the same machine;

Second, to receive the cigars as selected, arranged in superposed rowsand pressed, ready for boxing, feeding the cigars individually to thewrapping and banding mechanism and finally de livering the wrappedbanded cigars in the same order and without any rotation thereof so thatthey may be placed in boxes without rearrangement;

Third, to insure the placing of the band in a predetermined positionaround the cigar and to enclose the same by a transparent wrapperthrough which the band is plainly visible;

Fourth, to form the Wrappers from a continuous strip of wrappingmaterial, cutting the same to the exact lengths required and deliver-.ing each wrapper in exact registration with the cigar to be wrappedtherein;

Fifth, to maintain a continuous feed of the wrapping material from areel or source of supply and at an adjustable rate which will deliverthe length required for a single wrapper corresponding to the length ofthe cigar in each cycle of the machine;

Sixth, to provide an intermittent feed mechanism for the end'portion ofthe wrapper strip which holds the same stationary when severed to forman individual wrapper, and which takes care of the accumulating slack inthe strip during this period of rest;

Seventh, to deliver the band in registration with the cigar and wrapperand in such position that it will be inside of the wrapper when thelatter is folded about the cigar;

Eighth, to avoid. the necessity of using any adhesive in securing theband in proper position about the cigar;

Ninth, to simplify the mechanism which folds the wrapper about thecigar;

Tenth, to simultaneously fold theends of the wrapper over the body ofthe cigar and heat the same to hold said ends'permanently sealed.

With these and many other specific objects in view the inventionconsists in the construction as hereinafter set forth.

Generally described, my machine comprises 'a bed or supporting frame Imounted on suitable legs or standards 2 and having a motor 3 supportedthereon, preferably beneath the bed, and

by the suction feeders. At one end of the bed is mounted a transverselymovable receptacle 5 for holding the cigars in superposed rows asarranged for boxing and for intermittently delivering successive rowsinto position for feeding to the banding and wrapping mechanism. Thisfeeding mechanism includes parallel feed chains 6 extendinglongitudinally of the bed and upon which the cigars are carried to thepoint for successively registering'the same with their individualwrappers. The wrapper forming and band applying mechanisms are mountedon the bed respectively to the left and to the right as shown in Fig. 4.In general, these mechanisms function to simultaneously deliver awrapper and a band in registrationwith a cigar and in position to beengaged by the wrapping mechanism. This -wrapping mechanism performs itssuccessive Cigar row feeding mechanism In boxing cigars it is requiredthat each box should contain a definite number, such as fifty, arrangedin superposed rows or layers having a definite number of cigars in eachrow. Thus in boxes of fifty it is usual to have four rows or layerswhich are alternately of twelve and thirteen in each. It is also thepractice of cigarmakers to select the cigars according to color andother characteristics in arranging them in the rows for placing inboxes, this being done prior to banding and wrapping. Thus in handlingthe individual cigars during the banding and wrapping operations, it isquite essential that they should be maintained in the same order forreplacement in the box. To accomplish this I provide my machine with anexchangeable receptacle 5, Figs. 1, 4, and 6, corresponding in lengthand width to the dimensions of the box and adapted to simultaneouslyreceive the contents of one or more boxes. This receptacle is without abottom but in normal position is arranged above a shelf 8 on the bed andwhich supports the lowermost row of cigars. Periodically the receptacle5 is moved transversely of the bed, Figs. 21, 22, and 23, to carry thecigars off from the shelf 8 and over another shelf 9, which latter shelfis arranged between and on each side of the feed chains 6 and normallyabove the plane thereof, but below the plane of the shelf 8. Thus thelowermost row of cigars will drop below the plane of the shelf 8 withthe rear ends of the cigars adjacent to 8. depending stop flange orshoulder I thereon. The receptacle is then moved back to its originalposition which leaves the lowermost rows of cigars resting upon theshelf 9 while the next higher row will be supported upon the shelf 8.The shelf 9 is then lowered to rest the row of cigars on the chains 6.These are in constant movement and therefore as soon as the shelf 9 isdropped below the upper surface of said chains, the whole row of cigarswill travel with the chains to the left, as shown in Figs. 5 and '7.

The mechanism for accomplishing the opera- 5 tions just describedcomprises a pair of rods I l on which the receptacle 8 is mounted, theserods being slidably secured in bearings [2 on the bed and being providedon their lower sides with racks l3. These racks are engaged by 'gears Mmounted 10 upon a shaft I5 which shaft has also mounted thereon a pinion6 engaged by a gear segment I1 pivotally mounted on the bed. The gearsegment I! has a lever arm I I provided with a projecting pin ll whichengages a cam groove in a member l8 mounted upon a shaft I 9. Thearrangement is such that whenever the shaft I9 is rotated through onecomplete revolution, the lever arm H and gear segment I! will beoscillated, thereby imparting a rotary movement to the shaft I5 and tothe gear segments l4 thereon, which in turn through engagement with theracks l3 will reciprocate the rods H, carrying the receptacle 5 forwardand back by a substantially harmonic movement.

The movement of the shelf 9 is timed with the movement of the receptacle5 and is actuated by a cam 20 upon the shaft l9, which cam engages aroller 2| on a bell crank lever 22, Figs. 5, 6, and 20, the horizontalarm of which is attached to said shelf. The cam 20 is so fashioned thatthe shelf 9 is maintained in its raised position until thereceptacle 5has returned, after which it is quickly lowered.

In the pressing of cigars preliminary to boxing it is customary to placecardboard strips between superposed rows so as to prevent the embeddingof the cigars of one row into those of another. These cardboard stripsare left in' position when the pressed cigars are placed in thereceptacle 40 5 and during the delivery of the rows from the receptaclethe cardboard strips must be removed therefrom. This, as shown in Figs.6, 21, 22, and 23, is accomplished by placing upon the forward end ofthe shelf 8 a hooked shoulder 8 which is adapted to arrest the lowermostcardboard strip 8 during the forward movement of the receptacle. Theupper face of this strip 8 is rounded as indicated at 8 and 8 so thatthe cigars will pass thereover without obstruction both during theforward and return movement of the receptacle. I also preferably providea series of spring catches 8 on the forwardwall of the receptacle havingrearwardly extending tongues 8 for catching under the cardboard stripbetween the lowermost row and the next higher superposed row of cigars.These spring catches engage a stationary stop 8 when the receptacle isat the rear end of its movement so as to withdraw the tongues 8 andpermit the downward feeding of the cigars in the receptacle. However,during the forward movement of this receptacle the catches are withdrawnfrom this stop permitting the tongues 8 to project beneath the cardboard8 and supporting the same and the cigars thereabove while the lowermostrow drops upon the shelf 9. This shelf 9 extends not only between thechains 6 but is also provided with portions 9 outside said chains andconnected to the central portion by U-shaped loops 9 passing beneath thechains. The level of the shelf 9 in its uppermost position is below thelevel .of the shelf 8 and thus as soon as the lowermost row has passedover the stop 8 and beyond the shelf 8, it will cle the cardboard whichhas been arrested by the stop 8 is withdrawn from the shelf 8 by theaction of a friction shoe, preferably of rubber, 8 arranged on the rearwallof the receptacle and pressed downward against the cardboard on theshelf. The coefficient of the friction of this shoe being greater thanthat of the shelf 8, the cardboard 8" will be moved rearward anddeposited in a receptacle 8 from which it may be subsequently taken tobe used again in the pressing operation.

Driving and timing mechanism As has been stated, the reciprocation ofthe receptacle 5 is intermittent so that after depositing one row ofcigars it will permit this row to be fed forward by the chains 6 asufficient distance to clear the next row of cigars deposited on thechains. This necessitates a timing mechanism for controlling theoperation of the shaft I9, such that the shaft is only operated after apredetermined number of operations on the individual cigars of thebanding and wrapping mechanism, the construction being as follows.Power'from the motor 3, (Figs. 3, 5, and 20) is transmitted through achain 23 to a sprocket 24 upon a shaft 25 extending longitudinally andcentrally of the bed I. A clutch 26 is arranged between the pulley 24and shaft 25 under the control of a lever 21, by which the machine isstarted or stopped. From the shaft 25 movement is transmitted to aparallel shaft 25 through the medium of intermeshing gears 25 and 25 ata one-to-one ratio. From the shaft 25 movement is transmitted to aparallel shaft 28 at a one-to-one ratio through the medium of a chain 29and sprockets 38 and ti on the respective shafts. This chain alsoengages the sprocket 32 revolubly mounted on the shaft I9 but notnormally connected thereto. The shaft 28 transmits movement through agear train comprising intermeshing gear wheels 33 and 34, shaft 35, worm36 and worm gear 31 to a transversely extending shaft 38 on which aremounted sprockets 39 for a pair of feed chains 48. The chains 48 arearranged in the plane of the chains 6 and form extensions of the feedeffected by the latter chains. They are arranged to have portionsadjacent to and overlapping the chains 6 which portions then pass aroundsprockets 41 upon a shaft 42 and around idler sprockets 48 beforereturning to the sprockets 39. The chains 6 are driven from the shaft 42through the medium of a step-down chain drive 44 which connects asprocket 44 on the shaft 42 with a sprocket 44 on. a shaft 45, saidshaft having sprockets 46 for engaging and driv ing the chains 6. Thesechains then pass around idler sprockets 41 which are arranged at theforward end of the bed beyond the path of the receptacle 5.

With the construction as just described, it will be understood thatwhenever the shaft 25 is driven by the motor 3 it will communicatemotion at the same angular speed to the shafts 25 and 28 and that thelatter will communicate motion at greatly reduced speed to the sprockets39 which drive the feed chains 40. Motion is also transmitted throughthe step-down gearing chain 44' and sprockets 44, 44 to the shaft 45 andsprockets 46 which drive the chains 6 at a slower speed than the chains48. Still further motion is transmitted through the chain 29 to thesprocket wheel 32 on the shaft I9 but without normally communicating anymovement to said shaft.

To cause the operation of the receptacle 5 and its associated parts, thesprocket 32 must be coupled to the shaft I9 to drive the latter, butonly through a single revolution, after which it must be againdisconnected for a certain number of revolutions of the shafts 25 and28. This is accomplished by mechanism of the following construction:

48 is an internal ratchet wheel on one side of the sprocket 32 and 49 isa head on the shaft I9 carrying a pawl 58 which under certain conditionswill engage a tooth of the ratchet wheel 48. -Normally the pawl 58 isheld out of engagement with the ratchet teeth by a pin 5| slidablymounted in a bearing 52 on the frame and projecting into contact withthe pawl. The pin 5I is connected to a rack 53 actuated by a segmentalrack 54 on a lever 55 fulcrumed in the bearing 52, said lever beingconnected by a rod 56 with a lever 51 fulcrumed on the frame. Adjacentto this lever 51 is an index wheel 58 driven at slow speed through amechanism comprising bevel gears 59 and 68 communicating movement fromthe shaft 28 to a shaft GI, a worm gear 62 on said shaft in mesh with aworm wheel 63 on a shaft 64, a sprocket 65 on the shaft 64 and a chain65 communicating movement to a sprocket wheel 61 attached to the wheel58. The timing of this mechanism is such that for one revolution of theshaft 28 the index wheel 58 moves one-fiftieth of a revolution or onerevolution of the index wheel for fifth cycles of the machine. Engagedwith a plurality of the notches 58 of the index wheel 58 are cam dogs 68which at certain points in the revolution of said wheel will engage alug 10 on the lever 51. This will rock the lever 51 a sufficientdistance to withdraw the pin 5| from its engagement with the pawl 58,whereupon a spring 58 will force said pawl into engagement with theratchet teeth 48, coupling the sprocket 32 to the head 49 and drivingthe shaft I9. Before completion of one revolution of the sprocket 32,the cam dog 68 will have disengaged from the lug 10 so that the pin 5Iis again in the path of the pawl 58 and will disengage the same from theratchet 48. Thus each time the pawl 58 is tripped by withdrawal of thepin 5|, the shaft I9 will be turned one complete revolution and thenwill be again disconnected. This single revolution of the shaft I9 willeffect a reciprocation of the receptacle 5 and a lowering of the shelf 9as previously described, to deposit one row of cigars on to the chains6. The cam dogs 68 are spaced from each other so that the number ofcycles of the machine between engagement of said dogs with the lug 18corresponds to the number of cigars in one row. Thus in the case of afour row fifty-cigar box the distance between said dogs will bealternately twelve cycles and thirteen cycles. Consequently, when a rowof thirteen cigars is placed on the chains 6, thirteen cycles of theshafts I5 and 28 will take place before another operation of thereceptacle 5 to place a succeeding row on the chains. This next row willhave only twelve cigars and consequently there will be twelve cycles ofthe shafts I5 and 28 before another operation of the receptacle. Cigarsare also boxed in rows of two, three or five, with the total numberequalling 50. Adjustment of the index can be made for such boxes byproperly spacing the dogs 68 in the notches 58.

Wrapper feeding mechanism 1 of a dimension suitable for the width of awrapper. As shown, the roll of material is placed upon a reel II whichis mounted upon a bracket arm I2 extending upward from the bed I. Fromthe reel the strip passes downward between feed rolls I3 around an idlerpulley I4 on a rockable arm I5, and then between feed rolls I6 to extendhorizontally over a reciprocating carrlerYII. The length of the wrappersis proportionate to the length of the cigar to 'be'wrapped and as themachine is adapted for wrapping all cigars, the feed mechanism for thestrip must be variable. This is accomplished by driving the feed roll I3which is on a shaft I3 from a pulley I8 which in turn is driven througha belt I9 from a pulley 00 on a shaft 8!. This shaft is in alignmentwith the shaft 28 and is driven therefrom at the same angular speedthrough the medium of bevel gear wheels 82, 83, and 84. The pulley I8 iscomposed of two conical members It! and 18 which are adjustable towardsor from each other by means of a right and left screw threaded stud 18.This permits of changing the width of the space between the conicalfaces of the pulleys so that the belt I9 which is of a V-shaped crosssection will be located different radial distances from the axis of thepulley according to the adjustment thereof. Thus an adjustment of themembers 18" and 18 towards each other will enlarge the radius of theportion of the pulley engaging the belt and will slow the speed of theshaft I3 and feed roll I3. On the other hand, an adjustment of thepulley to separate the members I8 and I8 will permit the belt to assumea shorter radius and will increase the speed of the shaft I3 andfeed-rolls I3. The operator may therefore so adjust the pulley that thelength of strip fed by the rolls I3 in each cycle of the machine (onerevolution of the shaft 28) corresponds to the length of the cigar to bewrapped.

As has been stated, the strip passing through the feed roll I6 isdelivered upon a reciprocating carrier 11 which carrier is provided withsuction ports Il in its upper. face to retain the strip in contacttherewith. The operation of the feed rolls I6 is intermittent and theperipheral speed of these rolls exactly corresponds to the speed of thecarrier 11, which is greater than the speed of the feed rolls I3. As aconsequence when the feed rolls I6 are in action, they will take up theslack in the strip which has accumulated during the interval of rest ofthese rolls in the form of a loop around the vertically movable idlerpulley I4. As soon, however, as all slack is taken up, further movementof the rolls I6 is prevented although the carrier 1! may continue totravel. The strip is then severed to form a wrapper of the end portionthereof and the severed wrapper is then transferred into alignment witha cigar by mechanism now to be explained.

Mounted upon the bed I is a transversely movable carriage 93 which hasguide rods 94 slidable in bearings 94 and which as will be hereinafterdescribed, forms a transfer carrier for the cigars. This carriage isactuated by a rockable lever arm 95 pivoted at its lower end on adepending bracket 96 on the frame, and at its upper end connected by thelink 91 with the carriage 93. Upon the shaft 28 is a cam 98 foractuating a rod 99 pivotally connected to the lever 95 intermediate itsfulcrum and the link 91. This cam will therefore impart a substantiallyharmonic reciprocation to the rod 99 and through the lever 95 and link91 a similar movement to the carriage 93, with a dwell at each end ofthe movement of said carriage. Adjacent to the guide rods 04 for thecarriage 93 is a chain I00 (Fig. 9) which passes around a sprocket IN ontheshaft I02 of one of the feed rolls I6. At the other end the chainpasses around an idler sprocket I03 which is spaced from the sprocketIOI a distance greater than the travel of the carriage 93. Upon thecarriage 93 is a pawl I04 which rests upon the upper strand of the chainI00 and is adapted to engage a link thereof so that during the movementof the carriage 93 (to the right, Fig. 9), the chain I00 will be movedwith it, but during the reverse movement of the carriage (to the left,Fig. 9) the pawl I04 will slide over the chain without impartingmovement thereto. The pitch diameter of the sprocket IN is the same asthe diameter of the feed roll I6 which results in rotating said feedroll at a peripheral speed which is just the same as the speed of thecarriage 93. This driving of the roll is not, however, positive, but isaccomplished through a friction drive \mechanism as follows: Thesprocket IN is revoluble upon the shaft I02, but has arranged uponopposite sides of it friction washers I05, one of which bears against acollar I05, while the other lies adjacent to a gear wheel I 0'1, keyedto the shaft at I08 but longitudinally slidable thereon. I09 is a springbetween the sprocket I01 and a collar IIO on the shaft and which is ofa. tension to develop the desired friction between the washers I05 andthe sprocket IOI. The gear wheel I 01 intermeshes .with a gear wheel IIIon the companion roll I6 and the arrangement is therefore such that bothrolls IE will be frictionally driven by the sprocket IOI, if suchmovement is unres'sted. When, however, all of the slack in thecellophane formed by the loop around the idler roll I4 is taken up andthe arm I5 reaches the limit of its movement, then any further rotationof the rolls 16 is prevented. This is due to the fact that the rolls I3are rotating at a slower speed and the friction of these rolls upon thecellophane strip is greater than the friction between the sprocket IOIand the washers I05. It will, therefore, be understood that while thecarriage 93 always travels the same distance in its reciprocation andwhile the chain I 00 is moved the same distance in one direction, therolls I6 will only be operated by a portion of the movement of saidchain, dependent upon the adjustment of the rate of feed of the rollsI3. This permits of using the same intermittent feed mechanism for theCellophane" strip for all cigars without regard to the length thereof orthe length of the wrappers to be placed thereon. The reciprocatingcarrier 11 is formed by a bracket arm on the carriage 93 so that ittravels at the same speed as that of said carriage and the stripdelivered by the rolls I6.

To sever the wrapper from the strip shears II2 are arranged to extendtransversely thereof, these being normally open so as to permit thefeeding of the carrier 11 and strip therebetween. As has been stated,the carrier 11 has suction ports II 75 therein which retain the strip incontact therewith. However, the suctionis not sufficient to preventslipping of the strips upon the carrier 11 when the movement of theformer ceases and the carrier continues to travel. The effect is merelyto hold the strip taut while being severed by the shears. The shears areactuated by a cam II2 mounted on a shaft I I2 driven by the bevel gearwheel 83 and the timing is such that the strip is severed at thecompletion of the forward movement of the carriage 93 and before thereturn thereof. While in this same position the severed strip is liftedfrom the carrier 11 and deposited on the carriage 93 in registrationwith the cigar thereon, as will be later described.

Registration of wrapper with cigar and transfer of both to the wrappingmechanism As previously described, the rows of cigars intermittentlydeposited upon the feed chains 6 are advanced by said chains until theyare picked up by the chains 99 which are traveling at a higher rate ofspeed. The cigars on the chains it will be advanced until arrested by anadjustable stop I It. This is located at a point beneath the carriage 99which latter is of bifurcated form having the furcations 93* and 93spaced a sufficient distance from each other for the reception of acigar therebetween. As cigars vary in diameter, angle flanges 93 areadjustably secured to the furcations so as to space the vertical flangesthereof to correspond to the particular size of cigars operated on.Beneath the end cigar which is in contact with the'stop I I4 is anelevator M5, this being provided with slots II6 regisiering with thechains 40 so as to permit of lifting the cigar from said chains withoutinterfer-' ence therewith. To hold the succeeding cigars from movementduring such lifting of the end cigar, there is a hinged table II'Iarranged between the chains 40 which when moved upward will lift thecigars from said chains and press them against a yieldable resilientclamp II8. Thus during the lifting of the one cigar, all succeedingcigars in the row are held from movement but upon the return of theelevator II to its lower position and the dropping of the table lit, thecigars will again be advanced up to the stop I It. For accomplishing themovements just described, there is arranged upon the shaft 29 a cammember I I9 on one side of which is a cam I20 engaging a bell cranklever I2I connected by a link H22 with a table H1. The opposite side ofthe member H9 is provided with a cam groove for engaging a roller I23 ona lever I23 fulcrumed at i23 and having a segmental rack I23 which is inmesh with a depending rack I24 on the elevator II5. Thus the one camgroove will actuate the clamping table Ill and the other will cause theraising and lowering of the elevator. In its upward movement theelevator H5 will lift the end cigar into the space between thefurcations 93 and 93". An adjustable end stop I25 is arranged betweenthe furcations to engage the end. of the cigar and to exactly positionthe same, this stop being adjusted for cigars of different lengths.There is also an adjustable stop I26 for the end of the cigar while inengagement with the stop lid and which is aligned with the stop I25.

Prior to the raising of the cigar by the elevator I55 the wrapper whichhas been severed from the strip and is upon the carrier 11 is engaged byan oscillating suction head I27 which lifts it from said carrier anddeposits it upon the top of the carriage 93 so as to extend acrossfurcations and over the cigar. Suction apertures 93'? in the furcations93 and 93 serve to hold the wrapper in this position where it is inexact registration with the cigar ready to be wrapped therearound. Themechanism is so timed that after both the cigar and the wrapper havebeen engaged with the carriage 93 the lever arm 95 is actuated by thecam 98 to move the carriage forward, carrying with it both the cigar andthe wrapper. At the forward limit of this movement there is anadjustable stop I28 which engages the end of the cigar so that thelatter will be held between stops I25 and I28 while in this position.The suction head I2'I is mounted on an oscillating frame I21 theopposite ends of which are pivotally connected to crank arms I2! andI21". These are actuated by gears I2'I which' in turn are actuated bygear segments of longer radius I2'I connected to each other by the linkrod I21 One of these gear segments is actuated by a crank arm I2'I andconnecting rod I2'I from a crank I21 on a shaft I I2", which is drivenby the bevel gear wheel 83. Thus one complete rotation of the crank I21will rock the crank arm I2! and connecting mechanism so as to rotate thecrank arms I2'I and I2I through 180, thereby moving the suction head I21 from a position in registration with the wrapper on the carrier I'ito a position in registration with the carriage 93. The timing is suchthat the suction head I2I' engages the carrier 'II'I when at the forwardend of its movement (to the right, Fig. 9), and engages the carriage 93when in its rearward position (to the left, Fig. 9). Also, theregistration of the suction head with the wrapper on the carrier 11occurs prior to the severing of said wrapper from the strip by theshears I I2, thereby holding the wrapper from displacement during suchsevering operation.

Band applying mechanism As the cigar band and wrapper are to besimultaneously applied to the cigar, the machine must be provided with aband delivering mechanism which coacts with the wrapper deliveringmechanism. In my copending application for patent Serial No. 663,079,filed March 27, 1933, I have described one form of band feeding andapplying mechanism which is adapted to aflix a band to each wrapperbefore the latter is delivered in registration with the cigar. This samemechanism could be used in the machine forming the subject matter ofthis application but I preferably employ a simpler form of mechanism andone which dispenses with the use of adhesive for attaching the band tothe wrapper. This mechanism is arranged on the right hand side of themachine, Fig. 4, and cooperates with the mechanism for transferring acigar and a wrapper into registration with the wrapping mechanism aswill now be described.

The bands to be applied to the cigars are placed in a stack in a holder85 which is supported in inclined position upon the frame at the righthand side thereof. Adjacent to the lower end of the holder is mounted arockable suction head 86' which in one position is pressed against thelowermost band in the stack after which it is dropped downward to asubstantially horizontal position, the suction removing the band andholding it upon the head. The rockable suction head 86 is mounted on arock shaft 81 which is actuated by a rock arm 88 yieldably connected bya spring 8|! with the gear segment 89 in mesh
